Kit and assembly for compensating for coefficients of thermal expansion of decorative mounted panels

ABSTRACT

A wall panel attachment system for use with a vertically supported sub wall. Pluralities of horizontal and vertical extending and elongated profiles intersect to define an overall grid pattern. Each of the profiles exhibit, in cross section, a flattened base portion adapted to being secured to the sub wall by a plurality of fasteners. A web extends from an intermediate location of the base portion and in turn supports both an intermediate lip and an outermost spaced lip extending outwardly in both directions from the web. A plurality of panels each have a thickness separating front and back surfaces and surrounded by four interconnecting side edges within which are defined recessed profiles. The recessed profile edges of the panels seat the outermost spaced lips such that the back surface contacts the intermediate lip. The panels are permitted movement in multi axial directions in response to experienced coefficients of thermal expansion without buckling or warpage.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention discloses a kit, assembly, and installationprocess with hardware used for securing and aligning wall panels into afunctional and decorative array of arranged panels. The inventive panelsystem combines unique attachment mechanisms, layout, panel joinery, andaccommodation for building movement. Further, the system providesseveral unique means for securing the system panels within a systemframework, and for supporting the weight of each panel in such a mannerthat thermal coefficient's of expansion/contraction which are endemic togiven installation environments will not otherwise result in warping orbuckling of the panels at their mounting interfaces. The variousconfigurations depicted herein also provide a maximum of air circulationbehind the panels and which assist in avoiding mold or otherenvironmental degradation. The system, kit and assembly additionallyoffers unique advantages over prior art including faster installationtime, drastically reduced parts count and inventory requirement, theoption of individually demounting installed panels, faster and simpleralignment of panels over uneven walls, sound absorption of both high andlow frequency noise, interchangeability of decorative moldings, reducedmaterials cost, reduced installation cost, and superior ability toabsorb building movement including a unique provision for individualpanel movement to not affect or transfer any stress or movement to anyother panel within the same arrayed installation.

The inventive panel system also allows for the option of accommodationfor building movement while providing for simultaneous stable panelbearing support, and the option for system framework to remain incontact and alignment with all four sides of an installed panel, oralternatively (depending on the need parameters of the installation) thefourth (top) panel edge is adjacent a headspace of at least 1/32″ and asmuch as ¼″, providing room for an unbalanced, unconditioned, or unstablepanel to safely expand without disturbing other elements of theinstalled array of panels (see plastic spacer detail). Movement ofarchitectural components occurs either during normal seasonal movementof the building, or in the natural expansion and contraction of thepanels themselves by varying conditions of vibration, moisture, orhumidity. Additionally, the present system avoids the requirement fordrilling or otherwise machining the back side of the wall panels andprovides several different mounting methods within the same system,while maintaining a unique mix of features and benefits not previouslyknown in the art.

2. Background of the Relevant Art

Architectural panels are well-known in the art. Such panels differ frommost wall coverings in that they typically feature mechanical attachmentof some sort, or at the very least offer a thickness exceeding typicalwallpaper-type coverings and are therefore generally thicker than ¼″,and are most commonly 5/16″ to ¾″ in thickness.

Such panel systems are typically employed to conceal building wallirregularities and to protect and decorate wall surfaces in offices,hospitals, retail spaces, and building interiors. The panels are mostcommonly offered in wood grain, metallic, simulated grass, and otherfaux finishes. Substrate materials are most commonly plywood, woodflour, gypsum or other mineral (e.g. magnesium oxide, Portland cement)board, plastic, or combinations thereof.

Additional examples from the prior art include the panel attachmentsystems depicted in each of U.S. Pat. Nos. 6,427,408, 8,151,533 and6,202,377, all to Krieger. In the Krieger, '533 reference, a modularwall system includes a number of decorative panels that are received inan extruded panel frame. Each of the frames are positioned by connectingthem to a wall rail that is attached to the building. The wall rail andpanel frame each have a groove that accepts a fastener or clip byinterference or snap fit to attach the panel frame to the wall rail. Thegrooves have a dove-tail shape that permits a snap fit to secure thepanels, while permitting the panels to be easily removed orreconfigured.

In each of the Krieger '408 and '377 references, the wall systemincludes a plurality of rectangular rigid prefinished panels mounted ona wall support structure with main runners and cross runners. The mainrunners serve to lock the panels onto the support structure and with thecross runners serving to prevent the wood-based panels from warping dueto adverse moisture conditions. The main runners are configured to spacethe panels from the wall support structure to encourage uniform humidityconditions at the front and rear of the panels. Clips that secure thepanels to the main runners are fixed adjacent the top and bottom paneledges at different setoffs to obtain an advantageous nesting of panelsfor reduced packaging volume.

SUMMARY OF THE PRESENT INVENTION

The present invention discloses an improved panel system andinstallation process which uniquely maintains panel contact on all fouredges of its perimeter while simultaneously maintaining full planarbearing suspension of the panel weight and for allowing the panels toindividually expand or contract, such as according to a givencoefficient of thermal expansion associated with the panel beingsituated within a given environment. Panel edges may preferably beengaged at a 135° angle between the direction of the panel and theresistive force of the inventive molding, or without any resistive forceby way of the panel headspace allowance included between the molding'ssplines and at the top and/or one side edge of the panel by use of aplastic spacer within the inventive molding. A further distinguishingfeature of the inventive system is that the various supporting profilesengage the panels upon their outside edge corners or perimeter faces,and as opposed to by the panel ends as is accomplished in all prior artsystems, the effect of such an engagement feature being a compressiveforce which does not pull the panel apart, rather it acts to keep thepanel together while under stress, or elimination of the stressaltogether at the option of the user.

Additional variants associated with the present assembly includeproviding for individually demountable panels while using inexpensivereclosable fasteners which are individually mounted such as be reverseface adhesive strips to each of inner faces of the panels and opposingouter faces of the surface mounted profile extrusions or otherconfigurations, this in combination with the unique shaping of theprofiles providing mounting of one side of the reclosable fastener, withadditional vertically-oriented profiles establishing aligning contactwith additional mounted panels along each adjacent side. The revealprofile is provided according to a variety of different designs andmaintains contact along each vertical edge of each panel, even duringmovement of the panel or installation.

Demountable panels are also suspended in full bearing support alongtheir bottom edge, such as through the installation of an additionalelongated profile exhibiting a lip support lower edge which extendsproximate a floor location. Demountable installations exhibitingmultiple (two or more) rows of panels can feature a horizontal profileadjacent to the top running edges of panels.

Any of the profile configurations depicted herein can also exhibit atleast one surface which is either flush with or spaced a distance from asub-wall surface of the room (this defined as such as the underlyingwallboard or drywall material covering the joists and to which thedecorative panel assembly is mounted). In given applications, a sub-wallseparation distance of a panel supporting profile can be less than anadditional distance that may be accommodated by a reclosable fastenerwithout disengaging therefrom.

The numerous examples of the panel supporting and vertical/horizontalintersecting profiles and also include each of a vertical profilesupported upon a vertically-oriented dual seam strip. The dual seamstrip can be designed to include two columns of reclosable fastenersalong its length, with each column corresponding to a panel supportedadjacent to the molding's left and right.

Additional features can include the reclosable fasteners being flexible(or movable) in at least two, and preferably each of three (xyz)dimensions concurrent with expanding/contracting movement of thesupported panels. This is further accomplished in such a way as tomaintain edge spacing between the multiple panels. The materialconstruction of the various reveal profiles can also include, withoutlimitation, such as aluminum or other thin walled materials whichprovide a desired combination of support and, where necessary, somedynamic deflection or give. Variant of the profile constructions, suchas including the reclosable profiles described herein, can also beconstructed of a rigid plastic or composite material.

DETAILED DESCRIPTION OF THE INVENTION

With reference to the succeeding illustrations, the panel system and kitaccording to the several embodiments described herein provides bearingsupport for a plurality of panels assembled in a decorative supportedarray upon a wall interior and in such a way that the panels arepermitted to expand or contract according to their determined thermalcoefficient, such as resulting from a given set of environmentalconditions. As is also known, extended running lengths of assembledpanels and the underlying grid configured profiles required for mountingthe panels can multiply the degree of expansion or contract, such asvarying in intensity or degree over a significant time elapse notlimited to changing of seasons, with the result being that ananticipated set of dimensional changes not anticipated for in theoriginal installation can result in warpage, panel expansion, bucklingor inadvertent disengagement of the panels from the underlying supportstructure.

As will be further described below, the present invention provides eachof fixed and reclosable assemblies, the latter permitting individualpanels to be demounted from the wall assembly without interfering withthe remaining panel installation. Additional features of the presentsystem and assembly include the ability to bear all a given panelweight, the multiple supported rows of panels not touching the floorand, as such, capable of being employed up a wall's height to anydesired top end.

Referring initially to FIG. 1, a perspective view is generally shown at10 of a panel attachment system according to a first embodiment forcompensating for thermal coefficients of expansion of wooden orotherwise constructed decorative panels (see at 12 and 14). Withoutlimitation, and as will be described in additional detail with respectto succeeding variants, the decorative panels 12, 14, et seq. can beprovided in any plurality and with desired surface ornamentation. Aswill be further described, the panels each exhibit, without limitation,a square or rectangular profile with given crosswise dimensionscorresponding to the underlying profile grid assembled to support itand, as further shown in succeeding illustrations, exhibit a variety ofdiffering edge profiles designed to seat, support or abut with a varietyof differently configured wall mounted profiles.

The assembly mounts to a sub wall 16, such as including withoutlimitation any type of particle board or wall board material (and suchas without limitation encompassing materials known under the technicaldescription of gypsum or drywall). A plurality of joists or studs areprovided arranged in a manner for supporting the sub wall 16, such aswhich are depicted at 18 in each of FIGS. 1 and 3 and which can includeeither metal “C” channel shapes in cross section, as depicted, as wellas also including standard wood (such as 2×4) supports. The joists 18are position on the rear surface of the sub wall 16 (which is typicallysecured to the joist using screws, nails, fasteners, glue, etc.).

Given the above description, the present assembly includes the assemblyof a plurality of profile components in a number of grid definingconfigurations in order to securely and dynamically support the edges ofthe panels 12, 14, et seq. As shown in FIGS. 1 and 3, this can includeany number of vertically extending profiles and which is shown in crosssection, exhibit a double panel edge supporting profile including acentral most recessed area 20 through which are inserted any number ofscrews or like fasteners 22.

The double panel profile shown exhibits any elongated or heightextending direction (as best shown in FIG. 1) with a pair of wing orlateral portions 24 and 26 which respectively align with proximate andinner edge extending portions of the panels 12 and 14. Withoutlimitation, the profile (20, 24 and 26) is constructed of any suitablematerial not limited to an extruded aluminum or other lightweight metaland can also include durable plastics or other materials. As also shownin the crosswise depiction of the double profile, a plurality of subwall support feet 28, 30, 32 and 34 are located at each of opposite endand intermediate spaced locations (these being arranged in pairs todefine opposite lateral ledges of the wing portions 24 and 26).

As described, opposing pluralities of reclosable fasteners are providedfor mounting the inner faces of the panels 12 and 14 to opposing andsupporting surfaces established by the wing portions 24 and 26 of thedouble panel supporting profile. In one non-limited application, thesefasteners (see as depicted by a first pair 36 & 38 secured to outerfacing surfaces of the wing portions 24 and 26, as well as a second pair40 & 42 secured to inner facing and aligning surfaces of the panels 12and 14) can include a commercial product produced by 3M® under thetechnical name Dual Lock™ Reclosable Fastener.

The Dual Lock™ fastener system typically includes an elongated stripexhibiting a peel away adhesive backing for securing lengths thereof toany of vertical and/or horizontal extending locations of the profilesand panels. As further shown, the forward facing configuration of eachDual Lock™ fastener 36-42 exhibits a plurality of closely spaced bunchesof individually flexible elements, such as without limitation polyolefinstems, these exhibiting rounded/bulbous heads. Without limitation, thestem bunches are provided in a desired density such that, and upon beingintermeshed with an opposing stem bunch as best shown in FIG. 3, thepanels are each permitted a degree of lateral (see arrow 44 in FIG. 1)and vertical (arrow 46) independent movement (as well as potentially afurther degree of in/out movement as depicted by arrow 48 in relation tospecified panel 12 owing to the intermeshing configuration of the stembunches associated with a given inter-engaging pair of fasteners 36-42).

Without limitation other fastener constructions, such as variations ofhook and loop fasteners or the like, can be augmented or substituted forthose shown at 36-42 and without departing from the scope of theinvention. These can further include other reclosable fastener systemssuch as hook and loop and interlocking stem and interlocking islandsystems such as known under the commercial names Lynx™ and QwikGrip™,and the like.

Also depicted in each of FIGS. 1, 3 and 3A is a vertically extendingpanel edge supporting and displacement permitting component, see at 50,supported in abutting fashion, via inwardly turned end feet 52 and 54,upon inner spaced locations proximate the center location 20 of the dualedge mounting profile. As further best shown in FIGS. 3 and 3A, an outerfacing configuration of the component 50 includes angled sides 56 and58, these respectively contacting angled inner edges of the panels 12and 14.

Owing to the secure and multi-dimensional floating engagement affordedby the opposing pairs of fasteners 36 & 38 and 40 & 42, the inner paneledges bias and sandwich the vertically extending component 50 in amanner which retains the component 50 in contact with the exterior ofthe dual profile 20, while permitting the panels 12 and 14 a limiteddegree of independent or concurrent multi-axial motion in a manner whichdoes not introduce any strain or deformation, while also permitting theinner panel edges to move along the sloped profile edges 56 and 58 ofthe sandwiched component 50.

A floor proximate extending support profile is provided as shown at 60in FIG. 1 and exhibits a generally “L” or “J” profile in cross section.The component 60 is likewise constructed as an aluminum or durableplastic extrusion and is mounted to a floor proximate location of thewall, see as also depicted in FIG. 22 in which the floor extendingprofile 60 is mounted by nails or like fasteners 62 at a locationrelative to a floor 64, this so that a bottom lip 66 provides anelevated and abutting support to a bottom corresponding edge of selectedpanel 12. Additional features shown in cross section in FIG. 22 includea spacer block 68 positioned between the bottom surface of the sub wallattachable floor profile 60 and the floor 64, with a covering baseboard70 or like fascia provided for completing the decorative appearance.

As further depicted in each of FIGS. 1, 12 and 22, additional reclosablefastener strips are provided (similar in construction to thosepreviously described at 36-42) and include such as spaced apart strips72 and 74 attached to the outward facing vertical surface of the floorprofile, these being inter-engaged in dynamically and incrementallydisplaceable fashion by any number of opposing/aligning/matingreclosable fasteners attached, at 76, to the inner facing surface of thepanels (see as shown by panel 12). The floor profile 60 also includesfeet supports depicted at 78 and 80 supporting against the sub wall 16,with additional outer facing feet 82 and 84 bounding the reclosablefastener strips 72 mounted to the exterior face of the floor profile 60for defining an inward deflecting distance associated with the mountedpanels 12.

Referring further to FIG. 7, a cutaway side view is shown of anintermediate height located and horizontally extending profile 86 which,in combination with the floor proximate J-bar profile, supports oppositehorizontal extending edges of the panels 12 and 14. The profile 86 isunderstood to include one of a number of examples of horizontallyextending profiles which, in combination with the vertical extendingprofile 20, are arranged in vertically spaced and parallel extendingfashion such that they collectively define a sub wall affixed gridplatform for receiving any number of the panels 12, 14 et seq., inplural horizontal and vertical stacked rows.

The profile 86 exhibits a number of features similar to that associatedwith the floor profile 60 and includes an arrangement of support feet 88and 90 for leveling against the sub wall 16 upon installation offasteners 92 through apertures defined in the profile. A reclosablefastener 94 as previously described is adhesively attached to theexterior face of the profile in a similar fashion as previouslydescribed and so that an opposing (inner) facing reclosable fastener(see at 96 in FIG. 13) applied to an inner face of a further selectedpanel 12 engages the fastener 92 is secured in a consistently affixedand incrementally movable fashion consistent with that previouslydescribed.

As further shown, FIG. 13 is an illustration in side cutaway of a pairof stacked and horizontally extending profiles 12 and 12′, including theprofile 86 shown in FIG. 7 arranged in abutting fashion underneath afurther configured profile 98 which is secured to the sub wall 16 usingadditional fasteners 92 and which includes additional pedestal feet 100and 102 for leveling the profile 98. The lowermost foot 100 extends intoa bottom lip 104 which establishes a lower deflection point for theupper stacked panel 12′, uppermost inner 106 and outer 108 configuredportions of the lower horizontal profile 86 defining abutting locationswith the upper stacked profile 98 and for supporting the pair ofvertically stacked panels 12 and 12′ along opposing horizontal extendingedges (again FIG. 13).

As also shown, opposing reclosable fasteners 110 and 112 are secured,respectively, to the surfaces of the upper horizontal stacked profile 98and the inner surface of the upper vertically stacked panel 12′ and, incombination with the dynamic supporting arrangement provided by thelower situated panel 12 and the additional supporting structure depictedin FIG. 1, collectively provide for multi-axial alignment of the panels,such as in response to environmentally induced changes in dimensionresulting from the coefficient of expansion/contraction of the panels,this while maintaining a desired neat and orderly appearance to thedecorative wall structure as well as maximizing ventilation andbreathability of the panel to sub-wall interface in order to deter moldor the like.

FIG. 4 is a top plan view which is substantially identical to FIG. 3,with the exception that it depicts an alternate configuration of asandwiched vertically extending and panel edge supporting/displacementpermitting component 114 (this substituting for the earlier depictedcomponent 50 in FIG. 3). The supporting component 114, as depicted incross section, includes inner-most spaced apart and substantially “U”shaped support feet 116 and 118 which, in combination with the dynamicengagement established between the pluralities 36 & 38 and 40 & 42 ofthe reclosable fastener strips, provide for a degree of dynamic collapseand give to accommodate any thermal coefficient induced expansion orcontraction of the panels.

The decorative bulbous shaping of the support profile 114 is supportedin a similarly sandwiched manner between the inner edges of the panels12 and 14 and the central location 20 of the inner sub-wall affixedprofile. As further shown in FIG. 4, an inner circumferential lip edgeof the profile 114 (see at cross sectional locations 120 and 122) isdefined in an outwardly spaced fashion from the outwardly turned supportfeet 116 and 118 and collectively seats the inner planar edges of thepanels 12 and 14 in dynamically supported and multi-axially displaceablefashion.

FIG. 5 is a sectional cutaway of an alternate decorative configurationassociated with first 124 and second 126 wall mounted panels and whichincludes wood strips 128 and 130 mounted to reverse faces of the panelsfor supporting decorative elements (see capped fasteners 132 and 134). Apanel edge supporting profile is shown at 136 and is dimensioned toinclude spaced apart support feet 138, 140 and 142 which, in combinationwith an inner stepped configuration 144, provides a consistent surfacefor mounting against the sub wall. A “T” shaped projecting profile 146is depicted in a manner which seats the inner opposing panel edges inthe manner indicated.

FIG. 9 further shows a is a top cutaway view of a single panelsupporting profile 148 which is similar in function to the profile shownat 20 in FIG. 8 and, however which is limited to supporting a singlevertical extending edge of an associated stacked array of panels (notshown). As opposed to the double edge profile 20 of FIG. 8, the singleedge profile 148 of FIG. 9 is contemplated to be utilized at a locationproximate to a vertical wall edge where a final row of verticallystacked panels is situated. As with previously described profileconstructions, the single edge profile 148 is mounted by fasteners 150to the sub wall 16 (this again including either a particle board ordrywall material but which can also include a concrete or other solidwall construction). A reclosable fastener 152 strip is attached to anexterior facing surface of the profile 148 and which, consistent withother described profiles, can inter engage a mating and inner facesecured fastener (such as depicted at 76 in FIG. 12) which is secured toa selected panel 12. Without limitation, the single or double edgeprofiles of FIGS. 9 and 8 can also be supported in either or both ofhorizontal or vertical grid defining fashion for supporting a decorativepanel array in the manner previously described and shown.

Referring now to FIG. 2, an illustration is generally shown at 154provided of an alternate configuration of a cross shaped profile forsubstituting in place of the removable assembly of FIG. 1. Consistentwith the previously described variants, the channel configured profilesof FIG. 2, as well as those subsequently depicted in each of FIGS.11A-11D, 14-21 and 23-25, permanently mount an alternate array of panels156, 158 et seq., in an edge seating arrangement which differs from thepanels 12 and 14 depicted in FIG. 1.

In particular, the panels 156/158 each exhibit a recessed edge profile,see at 160 and 162, which differs from the flat edges of the panels 12and 14 in FIG. 1 and which mount the panels 156/158 in an edge seatingand multi-axial permitting fashion relative to the outer facing edges ofthe grid profile 154. In this fashion, the profile 154 permits thesupported panels 156/158 to move in a selected combination ofmulti-axial direction (up/down, left/right, in/out) to again accommodatethe thermal coefficients associated with the panel construction and isbest depicted in the operation plan view of FIG. 10 in which selectedstationary corner supporting locations (X), at 160 and 162 associatedwith panels 156 and 158 and, combined with arrow designations 164 and166 depicting permitted multi-axial and thermal coefficient of expansioninduced motion permitted the panels according to the several embodimentsdescribed.

With reference again to FIG. 1, in combination with FIGS. 11A-11D, thecross shaped profile 154 is constructed of a similar material aspreviously described and includes an inner sub wall mounting and planarlip or base portion 168. A web 170 extending from an intermediate andelongated surface of the base potion 168 supports both intermediate 172and outermost 174 profile lips. As shown, the profile lips 172 and 174are integrally formed with and extend in both lateral directions fromthe web 170 (see also opposite edge extending portions 172′ and 174′)for facilitating seating of channel defined edges, such as at 160 inFIG. 11A for selected panel 156.

A cross wise extending portion of the overall profile 154 as shown inFIG. 2 is identically constructed and referenced. A plurality offasteners 176 is provided for mounting the cross wise and grid definingprofile 154 upon the sub wall surface. As further depicted in each ofFIG. 1 and FIGS. 11A-11D, varying configurations are shown of integrallydefined embossments or protuberances, these for example shown at 178 and180 for extending in inner facing and spaced apart locations ofoutermost lip portions 174 and 174′.

As shown in FIG. 11A, the inner recessed edge channel 160 of theselected panel 156 seats the lip portion 174 such that the outer paneledge abuts the selected protuberance 158 in a manner which permits adegree of multi-axial displacement of the panel. Although not shown, anadditional panel can be installed in opposing fashion such that it seatsselected outermost lip 174′ in a like multi-axial and independentlydisplacement permitting fashion.

FIGS. 11A-11D additionally depict a progression of views for installinga panel supporting profile as depicted in FIG. 2. This includes, in FIG.11A, using a pencil or other marking instrument 182 for creating a levelvertical or horizontal edge to which a selected running edge of the baselip 168 is aligned and fastened (at FIG. 11B).

A cushioning strip 184 can be attached to an inner facing location of aselected lip 174 in proximate location to its integrally definedprotuberance 178, see FIG. 11C. Finally, and at FIG. 11D, a secondaryand independently installed supporting profile 186 can be providedaffixed to the sub wall 16 a spaced distance from the seating interfaceestablished between the panel 156 and the main profile 154. The profile186 includes a cushioned cap 188 which abuts an inner surface of thepanel 156 and which, in combination with the edge seating profileestablished with the main profile 154, allows for an additional degreeof inner abutting support to the panels while permitting two dimensionallateral motion of the panel combined with at least a minimal amount ofin/out movement in the third dimension.

FIG. 14 is an illustration in partial cross sectional cutaway of afurther variant of cross shaped and panel supporting profile, seegenerally at 190, similar to earlier variants depicted in FIGS. 1 and11A-11D. A base wall or lip 192 mounts to the sub wall (not shown) by asuitable fastener. An intermediate and elongated web 194 spacesintermediate 196 and outermost 198 lips in a similar arrangement, withthe lips extending in both directions from the web 194 in order to seatadditionally edge configured panels 200 and 202.

As further shown, the panels 200 and 202 exhibit inwardly stepped edges(see at 204/206 for panel 200 and further at 208/210 for panel 202). Acushioning strip 184 as previously described can be secured to an innerfacing surface of a selected outermost lip 198 and, in combination innerspaced protuberances 212 and 214 exhibited on the lip 198, provide forthermal coefficient of expansion induced lateral and in/out movement ofthe panel profile according to multi-axial directions. It is noteworthythat a variety of edge configured panels can be utilized with likevariations in the design of the profile (154 or 190) in order to seatthe panels in a desired multi-axial displacement permitting fashion.

FIGS. 15-21 each illustrate in partial cross section a further potentialvariation of a profile adapted for supporting a different configurationof panel. Without engaging in a repetitive description of commonelements consistently presented in each of the profiles, subsequentdescription will be limited to the variances in the arrangement of theintegral protuberances.

FIG. 15 depicts in cross section a similarly constructed profilegenerally at 216 and which exhibits, in an outermost web supported lip218, both inner and outer configured protuberances 220/222 and 224/226integrated into opposite extending locations of the outer lip 218 in amanner which seats an inner channel recessed configured panel (e.g. aspreviously shown at 156 and 160 in FIG. 11A).

FIG. 16 illustrates, generally at 228, a further variant in which a pairof inner protuberances, including rounded upper protuberance 230 andwidened and curved edge lower protuberance 232 are provided in outer websupported lip 234 and which, as shown, support an upper panel 156 in amanner such that its bottom outer edges is supported upon the web of theprofile, the lower protuberance 232 defining an end abutment with theopposing outer edge of the lower situated panel 158. As constructed, theprotuberance arrangement of FIG. 16 permits each of the panels 156/158to move in multi-axial permitting fashion.

Proceeding to FIG. 17, a selected profile is generally shown at 236 ofoverall similar construction and which in particular depicts each ofpointed 238 and rounded/bulbous 240 inwardly facing protuberancesdefined along inner facing locations of the outermost web supported lip242. In this fashion, a pair of panels as previously depicted at 200 and202 in FIG. 14 are capable of being installed in the manner illustratedand so that the outermost extending edge of the upper situated panel 202rests on the inner web surface between the outermost lip 242 andintermediate 244 web supported lips. The lower installed panel 200 isfurther depicted such that its upper/outermost extending edge abuts anunderside of the lower situated and rounded protuberance 240. As such,the panels 200 and 202 are permitted a degree of xy two dimensionaldisplacement within its mounting configuration established with thecross shaped profile 236, this combined with a further incrementaldegree of in/out third dimensional movement.

FIG. 18 is a repeat illustration of the profile previously shown in FIG.16 and in which a further narrowed thickness pair of panels 246 and 248each exhibit flattened edge profiles (similar to those exhibited by theremovable panels 12 and 14 of the embodiment of FIG. 1). The flattenededges of the panels 246 and 248 seat in a consistent manner to thatdepicted by the panels 200 and 202 represented in FIG. 17 such that theembossments assist in facilitating the desired multi-dimensionalmisalignment permitting motion of the individual panels, again oftenresulting from thermal coefficient induced expansion or contraction ofthe panel, and again doing so in such a fashion as to maintain agenerally consistent and appealing spacing between the various panelsover the constructed wall surface.

FIG. 19 is an illustration of a further selected profile 250, again of agenerally consistent overall crosswise profile, and which incorporates amodified single embossment 252 exhibiting a straight edge at an innercorner established between the outermost lip 254 and the intersectingweb 256. A cushion strip 184 as previously described is installedagainst an inner facing surface of an upper projecting portion of theoutermost lip 254 for seating a recessed channel edge 160 of a panel 156as previously depicted in FIG. 16, with a lower panel 158 seating, viaits corresponding recessed edge 162, the lower projecting portion of theoutermost lip 254 in such a fashion that an inward corner associatedwith the outer flat edge of the panel 158 abuts the angled protuberance252 in a collectively multi-axial misalignment permitting fashion.

FIG. 20 is an illustration generally at 258 of a further variant ofchannel seating profile exhibiting a further configuration ofprotuberance depicted upon an inner facing side of an outermost websupported lip 260. The protuberance exhibits an arcuate ramping surface262 extending outwardly from the central supporting web 263, the rampingsurface 262 converging into a raised surface 264 and sloping back, at266, along an outer seating edge until merging back into the outer lip260. A pair of cushioning strip 268 and 270 are also depicted mounted toinside facing surfaces of both upper and lower extending portions of theouter lip 260, and which assist in seating the inner recessed edges 160and 162 of the upper 156 and lower 158 panels, respectively, in a mannerconsistent with that previously described.

FIG. 21 is a further depiction at 272 of a profile extrusion largelysimilar to that depicted at 250 in FIG. 19, with the exception that thelinear and inner corner edge protuberance is substituted by a convex orbubbled profile, at 274, exhibited along the inner corner establishedbetween the outer lip 276 and the supporting web 278. Although notshown, additional cushioning strips can be installed in this variant inorder to modify the nature and degree of the seating and multi-axialsupport afforded the upper 156 and lower 158 panels.

Yet additional profiles are shown in each of FIGS. 23-25, each of whichdepicting an additional example of a variation in profile constructionwith different lip and integrated embossment profiles for supporting avariety of edge configured panels not limited to those previouslydescribed. In the example of FIG. 23, profile 280 includes inner facingprotuberances 282 (convex) and 284 (pseudo stepped) along inner facinglocations of an outermost web supported lip 286. An inner/concave cornerprofile 288 is further depicted at an opposing/outer facing surface ofan intermediate web supported lip 290.

FIG. 24 depicts, at 294, another variation of profile in which innerfacing corners 294 and 296 of an outermost web supported lip 298 arelikewise embossed in order to respectively depict a pair of mirrored andirregular stepped patterns for assisting in seating any of the panelconfigurations previously described. Finally, FIG. 25 depicts a yetfurther profile 300 in which like positioned inner embossments 302 and304 (identical in representation to those shown at 294 and 296) arecombined with additional outer convex/bubbled protuberances 306 and 308associated with the outermost web supported lip 310, such aconfiguration being particularly suited for seating recessed channelsedges of panels such as at 156 and 158 in FIG. 21.

Given the above reference descriptions, a variety of differentinstallation protocols and notes as to specific features are presentedas follows and which are intended to augment and further clarify theabove detailed descriptions as applicable to either or both thereplaceable panel configuration of FIGS. 1, 3, 3A, 4, 6-9, 12, 13 and22, as well as the non-removable configurations of FIGS. 2, 11A-11D,14-21 and 23-25. This includes the installation of seam support stripsplaced along the wall at given increments, such as without limitationevery four feet on center. These seam strips may be mounted up toone-half inch out of place, and even out of plumb, without compromise tofinal panel alignment and gap consistency. The seam strips are similarlyscrew-attached to the wall structure, preferably down their center sincethat is the most likely location for blocking or studs.

The dual seam strips, which feature two columns of reclosablezero-liftoff fasteners, may be cut down their center to make twosingle-row moldings. With the two major aluminum mounting componentsinstalled, the system is nearly ready for final install. The decorativeand aligning reveal profiles are then placed on the seam strip andsecured with a small amount of silicone. The aligning component of thereveal profile is the raised center rib or “hat” which helps theinstaller gauge the horizontal space between panels. The reveal profilealso aids in extra-system lateral load transfer to the sub wall in thatany outside lateral load applied to an installed panel face will thentransfer to the reveal profile as the reveal profile contacts the rearface of the panel adjacent to each long edge of the reveal profile andthrough the dual seam strip below and into the sub wall structure.

In this manner, the first wall panel is placed at one end of the walland aligned up along one edge with the spline. The next panel is alignedalong the other side of the spline and also detachably mounted with there-closable fasteners to the seam support. When the wall is covered withinstalled panels, a crown molding may be screwed though the top edge ofthe wall panels. Also along the top edge of wall panels is either asingle seam strip run horizontally so as to stabilize and help securethe panels, or a Multi-Row Support Molding or Reveal Molding for thesame purpose.

The multi-row support molding features an upper flange which is designedto be exposed. The reveal extrusion also features a central raisedsection that is designed to be exposed. Both exposed sections' exposedfaces are no more 0.035″ proud of the rear face of the installed panelso that the panel, during a time of expansion, may expand and partlyoverlap the exposed section of the adjacent molding without creating ortransferring any stress to an adjacent panel.

A panel system can also be provided which exhibits 6.3 mm thickmagnesium oxide board substrates, and flame-resistant polyolefin fauxveneers covering the substrate, and a 4 mm flexible spline set betweenpanels to create a vertical reveal between the panels. A divider moldingis inset on top of an aluminum seam strip. The upper width of the splinefeatures flexible elements such that it can accommodate buildingmovement such that rigid wall panels will not be exposed to undo stressor buckling forces while still maintaining contact with the panel edgeon either side of it.

Also desirous is that there be a flexible element, such as a plastic padbetween the rear face of each panel and the aluminum extrusion it ismounted to so that the panel will ideally yield slightly when an outsidetransverse load is applied to the panel and to further facilitate panelmovement without stress such as when a panel may expand and partiallyoverlap an adjacent exposed face of an extrusion. The 3M® Dual Lock®fastener comprises the flexible pad and the reclosable fastener in onecomponent, but the two components may be achieved separately such aswith conventional hook and loop fasteners with one side mounted to aflexible strip of plastic or by using rare earth magnets, which areeasily found with sufficient strength, also mounted with a flexibleplastic or rubber pad mounted to at least one side.

All screws and mounting hardware are concealed within the finished baseand/or crown moldings (such as depicted in the example of FIG. 22) andboth aluminum support moldings via recessed channels therein. Additionaloptions include a base molding covering the support channel, with acrown molding covering and securing the top edge of the panels into thestructure behind. Up to the entire bearing of the panels may besupported by the floor supporting profile 60 or associated supportreclosable fastener strips (e.g. at 72 and 74 in FIG. 1) along thebottom of the panels 12 and 14, while the panels remain slidinglyengaged upon such bearing support.

The zero lift-off reclosable fasteners are adhesively bonded to thealuminum support and seam strip pieces and to the backside of thedecorative wall panels supported by this system. Without furtherlimitation, the panel constructions as set forth in the aforementioneddescription may include, but are not limited to each of Phenolic, wood,plywood, MDF, Gypsum, MgO, concrete fiber, agri-fiber, and the like.

The reclosable fasteners are further understood to be oriented ninetydegrees from one another (see again as specifically shown in FIG. 12 at72 and 76) so as to maximize the alignment flexibility while maintaininga constant surface area of engagement between the panel 12 and the floor(or “J”) profile 60. In one non-limiting application, each fastenerlocation features a minimum of one square inch of fastener engagement.

The grid defining and aluminum profile framework as described above issecured to the sub wall or other surface structure via screwspenetrating into the wall structure behind the sheetrock. Nearly anydecorative surface or material may be used between the panels (such aswithin the typical 4-8 mm wide reveal, which may be from 1 mm to 16 mmwide overall). This can further include the use of brushed stainlesssteel, copper, aluminum, with decorative finishes applied to the revealmolding itself or an insert therein. The reveal molding being separatefrom the seam strip molding provides a simpler task of coloring anyreveal (such as shown at 50 in FIG. 1)

The various examples of system moldings and panels again feature aseries of interconnecting and engaging surfaces. Whether the panel edgeis non-machined, rabbet-edge machined, or two-spline (dado) machined,each serves to locate each panel within the system and provide for some(if not necessarily all) allowance for movement in any combination ofmulti-axial directions as facilitated by the moldings and profileconstructions. This in particular can be reflected in panel movementwhile acting upon the panel's outside corners and not upon the ends,such as known in prior art systems.

Each molding's second (middle) spline also serves to support the panelback side against lateral loads that may be applied to the system fromoutside forces such as a grab rail, or wall impact, etc. As such no loadoutside of the panels themselves, whether transverse or in line with thepanel, can ever impart any load into a dado to cause it to split orfracture.

The only movement near any panel dado is the flexing of one panel splinearound the “bead” of each molding and that load and movement iscarefully directed at an angle of 100-170 degrees (135+/−35) between thepanel and the molding and is never 180 degrees. Such an angle isfacilitated by either a convex curvilinear surface or an angled ramp orwedge-shaped surface between the two splines along the long edge of amolding. This includes a panel system intended for panels typically from6 mm (¼″)-12 mm (½″) thick solid phenolic, solid plastic, aluminumhoneycomb, up to ¾″ MgO, or MDF panel material, and a ¼″-⅜″ (ideally5/16″) deep spline to be securely set into the 5/16″-½″ (ideally ⅜″)wide section of each panel's perimeter (or at least two edges thereof),with the lower edge of the panel bearing 100% of its weight onto thesupporting molding directly below each panel containing the spline alongthat panels bottom edge.

It should be further noted that none of the panel's weight is focusedinto the panel dado or rabbet so the panel is not under any stress tosplit or crack. Various sections of the splines can also feature abead-shaped detail contacting the panel perimeter functioning to allowfor movement as the panel expands and contracts with environmentalchanges and/or building movement while still maintaining contact withthe panel's edges. This can be a double bead contacting both the frontand rear splines of the panel or, alternatively, can be exhibited by asingle bead contacting against the panel's rear spline only.

In each of the afore-mentioned variants, all screws and mountinghardware are concealed behind the visible moldings (e.g. see again at 50in FIG. 1 and further at 114 in FIG. 4). The entire weight of the panelis supported by the splined molding in contact with each panel's loweredge, with all panels remaining slidingly engaged upon such bearingsupport.

The inventive moldings are oriented around the perimeter of theorthogonal panels so as to engage all four of the panel edges whileapplying some compression forces to at least a portion of three of theedges of each panel to make a secure retention of each panel. Eachpanel's bottom edge also has a spline, but that edge does not flexaround any bead and bears the 100% of panel's weight on its spline.

With the moldings securing against the panels via a compressive force(as opposed to a tensile force as in all prior art systems), the use ofmineral-based substrates such as gypsum and cement boards such asPortland cement and magnesia cement-based panels become viable. Thisfeature allows such a system to compete directly againstfinished-in-place drywall (and other mineral-based panel-based) systemswhich are prevalent in construction today. A reason for this is thatmineral panels are not stable in tensile across their thickness, butonly in compression.

In one exemplary system, each vertical engagement is configured so thatthe molding is just touching the corresponding panel's exterior edge(not panel end) at a 135° angle. As a result, any panel movement causesa corresponding minor opening, closing and/or flexing of a correspondingsection of the molding's two splines upon or the panel's spline, andsuch contact occurs along the panel's exterior edges.

The top (horizontal) edge of each panel supplies 100% of the verticalallowance of expansion and contraction, which may vary depending on theheight of the panel. For this reason, the reclosable variant of thepresent system may be used to allow for greater room for expansion.

Additionally or alternatively, greater vertical clearance may also beallowed for by eliminating the bead of the upper panel and using theinter-spline clearance as space for the panel to move. Setting thisrevised Horizontal Reveal in place is referenced by either a referenceline machined into the molding or via a flexible plastic spacer set onor adjacent to the top edge of the panel prior to engaging such as ahorizontal extending reveal or molding.

As in all of the inter-related variants of the fixed and removable panelembodiments of the inventive system, the aluminum framework is securedto the structure via screws penetrating into the wall structure behindthe sheetrock, and possibly a small amount of adhesive. In thereclosable variant of the inventive system (FIG. 1) the exposed sectionof the reveal moldings can include a decorative feature of the systemwhich may further be painted, coated or anodized as desired. The exposedreveal (e.g. again at 50 in FIG. 1) may be nearly any dimension notlimited to 4-10 mm up to generally 30 mm in width. As is shown, adecorative tape or a “T”-shaped insert may also be used.

The splined variant of the inventive panel system uses very few simplecomponents to provide performance and benefits beyond that of what isavailable from the very complex prior art systems today. The system caninclude, in one non-limiting application, a plurality of up to fivemoldings (horizontal reveal, vertical reveal, inside corner, outsidecorner, starter), with the horizontal reveal molding being the onlymandatory component. The horizontal reveal, in it's headspace-allowancevariant form may be used to replace both the vertical reveal andseparate horizontal reveal moldings as depicted.

The panels of the inventive system further do not require that they bedrilled or fabricated on the rear face which alleviates the requirementof flipping and re-orienting the panels in a CNC machine (or subsequentmultiple operations with a shaping tool) and, with only one component(molding) at each location, there is no requirement to reference onecomponent's location against the other within the system. In thismanner, installation is greatly simplified and makes the system trulyfield fabricatable and install-able by non-specialized, local workers.

Other considerations include the inventive system variant flexingoutside of any cut or machining of the panel edges, such that itmaintains constant contact via a safe and stable compressive force uponthe perimeter edges even during movement. Further still, the presentsystem provides additional lateral support against loads imparted to thepanel by means outside of the dado or machined panel perimeter, whereinthe panel is at full thickness, full strength, and has no crack startersor cuts into it.

It is again notable that the present system primarily engages the paneledges and not on their ends. By engaging the panels at their edges andnot on any panel end (except for the lower panel edge for bearing asdepicted by example in FIGS. 19-21) but along only the exterior cornersof the edges themselves, this manner of engagement is then across a lineand therefore has no surface area (or at the very least minimalgeometric surface area), and therefore has the least resistance tomovement as the panels swell and move in a natural way.

In this manner, a lineal engagement is focused at an angle of typically135°+/−25°, and is generally not less than 120°, and generally not morethan 150°, but may be as much as 170°, and as little as 100°. Bydeflecting the forces from movement into the interior face of the rearspline of the inventive moldings (90°/lateral orientation from the planeof the panel installation), the resultant and inevitable forces ofexpansion are not allowed to accumulate from panel-to-panel, as theywould via a typical prior art system featuring 180° engagement.

It has been found that this non-lineal angled engagement is an importantpoint since the panel's bearing is focused across an area (and not inlineal fashion) so the panel's forces are not additive from one panel tothe other, and so the location of each panel remains substantiallyconstant and the panel only moves as it swells or shrinks with changesin ambient moisture or temperature or as the building itself moves,along the three non-load bearing edges. This uniquely creates a movingpanel with a constant location that accommodates such movement withinthat location. It is also noteworthy that the present system also doesnot require the panels to be secured by some secondary means to precludethem from wandering out of place along the wall.

By obviating the need for an adhesive bed to retain the panels, as withmost C.E.G. installations, the present system eliminates many of theextraneous components associated with the prior art. The present systemis also stock-able at multiple locations which can be sold directly tothe persons performing the work, thereby reducing cost, lead times, andthe necessity for jet and truck travel around the country to performinstallations.

Further still, the panels that are to be retained into the system do nothave to be shipped to a common location with the moldings so that theycan be fabricated and referenced against one another and then re-shippedto the job site. This saves significant travel, and the cost andenvironmental impacts therefrom.

It has also been found that the present system is very forgiving duringthe installation process and can be designed so that the panels arrivefrom the original location, with the hardware being shipped inseparately, thereby reducing logistics requirements from multipleshipping of the typically very heavy and bulky wall panel materials. Itshould also be noted that the combination of the elimination of thedouble shipping of the panels and the elimination for the need of aspecial crew to travel across the country to perform the installationgreatly reduces the carbon emissions associated with this system.

A final variation in use of the splined variant of the inventive systemis that is can be mounted directly to the building subwall studs,obviating the need for drywall sheathing—saving much time and cost incommercial or residential construction. In such an application, aplurality of up to four studs are engaged by every four foot wide panel,with the first and fourth studs receiving an inventive splined moldingscrew-attached directly to them, and the middle two studs (studs two andthree) being first covered by a batten so that may serve either or bothof two purposes: to space the panel in parallel fashion equal with thetwo splined moldings, and to spread any applied lateral forces from thewall panel across a wider surface area by the battens typically beingabout 6″ wide rather than the stud faces being only 1.5″ wide. Lastly,this system is applicable in a single panel row usage, and in which thepanel weight is supported by an integral base molding which may be madeof composite concrete fiber, wood or plywood, plastic, or otherequivalent material.
